Most of the perks for a FC seem to involve buffs so it makes more sense for a FC to be based on progress leveling and instances. Guild housing is nice but players by the sound of it will have the chance to have their own place anyway. I can see a few situations where a FC might be used for RP only but for the most part they benefit player advancement so much it'd be a waste not to use it for that.
The LS provides links to other RP'rs and a place to have collective RP through your own chat channel and you can have more than one so it makes more sense to use those for the RP end instead of throwing all your eggs in one basket.
